In China, companies often select telephone numbers that sound similar to words or phrases that can be associated with their business/products.

The local number for a restaurant reservation hotline is 57-57-5777, which is pronounced 我吃我吃我吃吃吃吃 wǔ-qī-wǔ-qī-wǔ-qī-qī-qī and sounds similar to wǒ-chī-wǒ-chī-wǒ-chī-chī-chī (in English: I-eat-I-eat-I-eat-eat-eat!)
